CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 263,653, dated August 29, 1882, Application filed June 19,1882. (No model.)

To all whom it'mayconcern:

'Be itknown that I, EDWARD CASPER, a

- citizen of the United States, residing at Collomsville, in the county of Lycomingand State of Pennsylvania, have invented certain new and useful Improvements in Oar-Gouplings and I'do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1' is a perspective view of this invention, but showing the stop raised in both draw-heads, and also both forms of the lifting device. Fig. 2 is a longitudinal central section of Fig. l, but showing the link as in ordinary position in use. Fig. 3 is a cross-section on line 3 3 Fig. 2, to show construction of the stop; Fig. 4, details of stop on linear: m, Fig. 2; Fig. 5, detail of coupling-pin.

This invention belongs to that class of devices known as railroad-car couplings, and the novelty consists in the special deta ls of the construction and arrangement of tl c several parts, all as will now be more fully and in detail set out and explained.

In the accompanying drawings, A denotes any ordinary draw-head, and B the couplinglink. Inside of each draw-head is the stop 0, which is a flat piece of wood or metal of suitable shape and size to fit on the bottom of the chamber a of the-draw-head. It is so fitted at the back side by hinging or otherwise that it can have motion on this end. The front part extends forward near to the mouth of the draw-head. Here it is cut out, as indicated at 0. By this construction, when the stop is raised, as by lifting piece D or lever D, it will offer at c a suitable stop and sup port for the end of the link (J, as is shown in Fig. 2. When the link is thus in position it is secured there by the couplingpin E. This pin fits loosely in the socket a in the top and near the mouth, and in such a manner that when the link B rests in the chambered or grooved end cot the stop there is just space enough for the pin to drop through the end of the link. This pin has an upwardly-projecting part, c, which can be used as a handle. In this position the link is ready for entering the mouth of the draw-head of the car which draw-head, so that when the link is held in one draw-head, as has been above described, it will readily enter the mouth of the drawhead of the other car, knocking back and up the pin as it enters the month, so that thepin is turned up against the inside of the arch a and allows free passage for the link to enter the draw-head, and when the link is in the pin drops easily into the end of the link. In this way, which is that of ordinary use, and as now shown in Fig. 2, one end of the link has some motion inside the draw-head. The lower end of the pin E, being stopped by the forward edge of a on thelower side of the mouth, can have no forward movement.

If desired, there may be some guide-pins a on the outer side of slot a. Connection may be arranged from the lifting devices D or D to the top of the car, so that the brakeman can easily manipulate this pin, as for unshackling.

This device can be very cheaply made, and the several parts are all peculiarly strong and notat all liable to get out of order in any ordinary use, while for all the conditions demanded in such a device this coupler is very effective and certain in its operation.

Having thus described my invention, what I consider new, and desire to secure by Letters Patent, is-

1. The swinging coupling-pin. E, having journals c and handle 6, combined with drawhead A, having socket a. and arched chamber a substantially in the manner shown and described.

2. The draw-headA, having arched top a socket a, and chamber a, combined with the stop 0 on the floor of said chamber, hinged or jointed at its rear end and having the groove or chamber 0 at its front end, and movable by a lift and pin, E, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
